Expert writing Tips

Best practice

Use "supposed to" to clearly indicate expectations, obligations, or common beliefs. For increased clarity, ensure the context provides adequate information about who or what is imposing the expectation.

Common error

Avoid mistakenly using "supposed to" in place of "used to". "Supposed to" indicates an expectation or obligation, while "used to" describes a past habit or state. For example, use "I am supposed to submit the report today" (obligation), not "I used to submit the report today" (past habit).
